Gender: Men's, Women's Accessory: Surf Boots 25cm Mutant boots with a rounded toe for increased warmth and waterproofness. The lining uses Fire Wall 24, a stretchable, heat-generating brushed material similar to semi-dry suits. It offers warmth and flexibility, doesn't hinder subtle trimming during riding, and fits well with a Japanese foot shape. The 5mm thick instep and 4mm thick heel make it easy to put on and take off, providing a moderate hold on the entire foot and not interfering with subtle trimming.
